Receiving scam calls daily - Same first three digits

I'm a participant level 3

Hello Fido Community / Customer Service Reps,


I have been a loyal customer of Fido for quite a few years now and I know I'm not the only person experiencing this, but it's becoming a real nuissance: I have been receiving calls on a daily basis from phone numbers that just happen to have the same first three digits as mine (obviously, not including the area code lol). These are always either scam calls (always automated) regarding "purchases I've made", and on occasion, from actual individual, innocent people who claim they missed a call from me (when I did not call them). This cannot be a coincidence and I am 99% certain it must have something to do with how you are using my information...and apparently you have the ability to make calls to strangers on my behalf without it showing up in my call logs. 


I have already put myself on that Do Not Call List, and I block every single one of these phone numbers but it just doesn't stop.


I just hope there is something you guys can do on your end about this, because it is beyond bizarre and very concerning.


Thank you for your time!

Hello NatAttack,

  You're right (at least partially), it isn't a coincidence. However, Fido isn't selling or misusing your information nor have they had any security breaches. I think they are SPAM or SCAM calls from spammers/scammers using spoofed numbers. Unfortunately, there currently isn't much that any of the mobile providers can do to prevent them. Since the spammers/scammers use spoofed numbers, it is not possible to identify the true spammers' number. The numbers shown on caller ID do not belong to the spammers. They often belong to innocent, unsuspecting people, like yourself. That's why you've received calls from people thinking that you've called them. Your phone number showed on their caller-ID. There isn't much that can be done to prevent numbers from being spoofed. Even the RCMP are not immune to being spoofed (see here). 


  The spammers/scammers will tend to spoof phone numbers within their target range to make potential victims think the calls are coming from people they might know. Since your area code/prefix is for Fido (unless you ported from another provider), many of the calls will also appear to come from Fido phone numbers. It's called Neighbour spoofing (see here and here). In some instances, the spammers/scammers will use the recipients' own phone numbers to make the calls, called mirroring. Those are just the phone numbers the spammers/scammers chose to spoof. Unfortunately, there isn't much that can be done to prevent numbers from being spoofed. 


  The mobile providers have implemented Universal Call Blocking which is meant to block calls from malformed phone numbers. That said, I'm doubtful whether it will have much of an effect on the amount of SPAM or SCAM calls since many of them appear to have properly formed phone numbers. In addition, a new technology, STIR/SHAKEN (Secure Telephone Identity Revisited/Signature-based Handling of Asserted Information Using Tokens) is being adopted to further reduce the amount of nuisance calls (see here). However, I have my doubts as to whether those measures will reduce the amount of SPAM calls. My understanding is the STIR/SHAKEN will only identify possible SPAM calls and mark the calls as suspected SPAM.


  Unfortunately, until the technology to unmask the true number of spammers/scammers is readily available (not simply the number shown on the caller ID), the only solution currently is to block the numbers on your phone. You should note that blocking the calls only prevents the calls from ringing your phone. It does not prevent the callers from leaving voicemail. There are (at least were) some apps which claimed to also prevent callers from leaving voicemail. They worked by answering and almost simultaneously ending the calls. While those apps do prevent calls from going to voicemail, the calls are also considered 'answered' and therefore count as airtime.


Hope this helps 😀
